This chapter is from the book

Angular is a perfect client-side framework for most web applications because it provides a very clean and structured approach. With a clean, structured front end, you will find that it is much easier to implement clean, well-structured server-side logic.

This chapter introduces you to Angular as well as the major components involved in an Angular application. It is critical that you understand these components before you try to implement an Angular application because the framework is different from more traditional JavaScript web application programming.

After you get a good grasp of the components of an Angular application, you’ll learn how to construct a basic Angular application, step by step. This should prepare you to jump into the following chapters, which provide much more detail on implementing Angular.

Why Angular?

JavaScript is a powerful programming language that allows developers to use a web browser as a full application platform. Angular provides a great framework that makes it faster and easier to create client-side JavaScript applications. Developers use Angular because it provides a lot of the structure of web applications—such as data binding, dependency injection, and HTTP communications—that teams would otherwise need to develop themselves.
